"What would happen if I'm going to change them"

What would happen if I'm going to change them

Is this sentence correct? If we change it to "if I were going to," will it be strange?

It definitely seems odd as it stands. A subjunctive seems called for, but your suggested change is odd also. I'm not sure why. The normal expression is

What would happen if I changed / were to change them?

I suppose that nothing would happen if you are/were going to change them (relative future); something would possibly happen only after the change was effected.

Thanks Mister Mic.

What would happen if I were going to change them and acted accordingly.

Would this be still a little strange?

Interesting. Semantically, it seems more reasonable, certainly. I hesitate to try to analyze the syntax, though.
